MARSHALL O. LEFFERTS, OF NEW YORK, N. Y., ASSIGNOR TO THE CELLU- LOIDMANUFACTURING COMPANY, OF SAME PLACE.

MANUFACTURE OF SPOONS AND FORKS FROM CELLULOID AND ANALOGOUS MATERIAL.

SPECIFICATION forming part of Letters Patent No. 235,954, dated December28, 1880.

Application filed November 2 2, 1880. (No specimens.)

To all whom it may concern:

Be it known that 1, MARSHALL G. LEF- FER'IS, of New York, in the countyof New York and State of New York, have invented a new and usefulImprovement in the Mannfacture of Spoons and Forks from Celluloid andAnalogous Material, of which the following is a specification.

The invention relates to improvements in spoons and forks, and isintended to obviate numerous objections to certain classes of thesearticles now generally in use.

It is well known that all kinds of spoons and forks, especially thosemade of the most approved materials, are discolored by use in connectionwith acids, certain kinds of medicine, vinegar, mustard, &c., which is avery serious objection, that has not, as far as I am aware, beenobviated by any known expedient. hi the case of acids, it" the spoon bemetallic there is great danger of its being permanentlyinjured, andunless the bcst'material is used the acid is likely to be affected to agreater or less extent. To obviate these and other objections, and toprovide a spoon or fork which is commercially new, and which is in manyrespects exceptionably desirable, is the object of my invention.

The novelty of the invention consists in forming the part or parts ofthe spoon or fork which areliable to be subjected to the acid or othersubstance of celluloid or'analogous commay be formed of iron, wood, orother appropriate material, and coated with celluloid or 5 othercompound of pyroxyline in any convenient way. It made in a single piecethe article may be formed in a die or mold in any known manner, orotherwise treated, according to the circumstances of the case. If the 0shank or other part of the article is made or strengthened by employinga piece of metal or other material, the piece of metal or material maybeincorporated with the article during the process of manufacture, or maybe added afterward, as may be practicable.

It is obvious that the method of manufacture and the means ofeffectuatin g the objects of the invention are very numerous, and theywill be understood without explanation by 6o persons skilled in the artto which the invention relates.

I contemplate practicing the invention, especially in connection withthe manufacture of medicine, egg, pickle, olive, mustard, salt, andsalad spoons and forks, and in connection with other classes to whichthe invention is adapted.

I do not limit myself to anyparticular mode of manufacture, nor do Iconfine my claim to an article made wholly of celluloid or othercompound of pyroxyline; but

What I claim as new is- A spoon or fork the bowl or tines of which aremade wholly or in part of celluloid or 7 5 other compound of pyroxyline.

In testimony that I claim the foregoing improvement in manufactures ofcelluloid and analogous plastic material, as above described,

I have hereunto set my hand this 12th day of November, 1880.

MARSHALL U. LEFFERTS.
